Abstract The aim of this study was to determine the essential element (Zn, Ca, K, Fe, Na, and Mg), essential trace element (Co, Mn, Cr, and Cu), and non-essential element (Pb, Ni, and Cd) contents of eight different Russula species (R. risigallina (Batsch) Sacc., R. cyanoxantha (Schaeff.) Fr., R. delica Fr., R. vinosa Lindblad, R. olivacea (Schaeff.) Fr., R. velenovskyi Melzer & Zvára, R. turci Bres., and R. parazurea Jul. Schäff.) collected from Soguksu National Park (Turkey), which is a region away from the city center (Kizilcahamam, Ankara). In addition to the metal contents of these species, daily intake and health risk index values of the metals in question were also calculated and discussed. As a result of elemental analysis, the major elements were K (28980– 58,380 mg/kg), Mg (704–1404 mg/kg), and Ca (190–1662 mg/kg). Except for R. risigallina, R. olivacea, and R. velenovskyi, elemental concentrations were within the limits that can be safely consumed as nutrients in terms of their metal content. The daily intakes of metal (DIM) values of R. risigallina and R. olivacea for Cr exceed the reference dose limits (3.80 and 3.87 μg/kg body weight/serving, respectively). According to the health risk index (HRI) measurements, the HRI values of R. risigallina and R. olivacea for Cr and of R. velenovskyi for Cd were found to be above 1.0 and could pose a health risk. In order to analyze the mineral composition variability of the studied mushroom species, principal component analysis (PCA) and the hierarchical cluster analysis (HCA) techniques were also performed. Regarding the significant correlations between all descriptors (r > 0.7), there was a positive relationship between Mg–K, Ni–Co, Ni–Na, Cr–Ni, Cr–Co, Zn–Mg, Zn–K, Cd–Mg couples.

Introduction Highlights • Metal contents and health risk assessments of eight Russula species were studied. • Except R. risigallina, R. olivacea and R. velenovskyi, the samples were safe for the consumers. • DIM and HRI values of R. risigallina and R. olivacea exceeded the legal limits. • HRI value of R. velenovskyi was also found to be high than 1.0.
